5.8 Tricuspid atresia

Tricuspid atresia is a rare defect in which the right AV (tricuspid) valve is poorly developed or imperforate. In the early fetus, this defect may not have severe consequences because blood can pass through the foramen ovale, left AV valve I the primary interventricular foramen to perfuse the lungs. For the fetus and neonate to survive, it is essential that this pathway remains patent, particularly 'r birth when blood flow to the lungs dramatically increases. An ASD and a D are therefore part of this complex anomaly.
